Revealing mistake: When Will Scarlet finds the injured Much in Sherwood Forest about three quarters of the way through the movie, a white vehicle can be seen travelling from right to left in the background.

Revealing mistake: At the end, when Guy loses the sword fight with Robin Hood, his body topples over a parapet and falls to the stone floor below. In the initial shot of him falling, it's a stunt man (who apparently broke his ankle in the process, according to the dvd commentary), but the next shot of the body landing makes the use of a dummy a little too obvious: the "corpse" bounces back up several inches before settling to the floor.

Revealing mistake: At the end of the fight on the log between Robin and Little John, John's quarterstaff bangs down onto the log some distance away from the foot (of Robin) it is meant to have stabbed.

Listen carefully to the sounds the swords make during the final battle at Nottingham castle. When Robin and Sir Guy are fighting, they sound different (clanging as opposed to clicking) than all the other combatants. The reason for the discrepancy is simple. Errol Flynn and Basil Rathbone, both experienced performers, are using real steel swords for their one-on-one fight scenes, while everyone else is using plastic props.
